IMPROVEMENT lN STRlPPER-SPRINGS FOR CARDlNG-ENGINES.

Specification forming part of Letters Patent No. 217,575, dated July 15,1879 application filed April 5, 1879.

To all whom it may concern:

Be it known that I, FRANK A. BOWEN, of Putnam, in the county of WVindhamand State of Connecticut, have invented a new and ImprovedStripper-Spring for Cardin g-En gines, of which the following is aspecification.

The invention consists in combining a socket, base, sleeve, and rubberspring, as hereinafter described.

In the accompanying drawings, Figure 1 shows the .manner of applying thespring to the stripper. Fig. 2 is an enlarged view, in section, of thespring; and Fig. 3 is an end View of the spring in its socket.

Similar letters of reference indicate corresponding parts.

The stripper in carding-machines travels back and forth over the cards,and when it gets directly over one of the flats it stops, the tlat islifted and bears against springs attached to a cross-bar, while the armpasses under the flat, which drops down on the clothing on the arm. Thisnow draws back and the fiat is stripped, when the stripper moves on toanother flat.

In carding-machines at present the flat, when it is raised, bearsagainst two steel springs attached to the cross-bar; but these springsfrequently break, causing loss of time, and sometimes tear the clothingof the cards.

My invention is intended to remedy these defects, and to furnish asteadier and altogether better spring for the purpose.

Referring to the drawings, A represents a metal socket rising from aplate, B, having countersunk screw-holes a a.

C is the cylindrical rubber spring, placed in the socket A, and securedtherein by a screw, 1), passed through the barrel of the socket into thespring. The end of the spring projects out of the socket, and is fittedwith a metal A spring of this kind is not liable to break,-

does not mar the varnished surface of the flat, and holds the flatsteadier than the steel springs, as the rubber clings more closely tothe flat and does not slip, thereby preventing in a great measure therocking motion that the steel springs allow.

I am aware that it is not new to use a doorstop composed of aspring-actuated plunger sliding in a hollow stop attached to the wall,or to use a ear-bumper consisting of a plunger forced outward by aspring.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent The socket A and base B, in combination withsleeve 0 and cylindrical rubber spring C, secured in the socket by theset-screw b, as shown and described, for the purpose specified.
